Description
Product Overview

The Masoneilan 12800 is a pneumatic level controller that uses the torque-tube displacer principle to measure and control liquid level in process vessels. It combines the proven 12400 transmitter mechanics with a pneumatic controller to provide direct on/off or proportional control without electricity. It's widely used in refineries and chemical plants where pneumatic systems are preferred for safety or simplicity.

Features
  • Torque-tube displacer design – no process seals
  • Pneumatic output for direct valve control
  • Adjustable proportional band and reset
  • Local setpoint adjustment
  • Wide range of displacer materials
  • High pressure/temperature capability
  • Simple, no-electronic design
Technical Specifications
  • Measurement Range: 356 mm to 3048 mm (14" to 120")
  • Process Pressure: Up to ANSI Class 2500 / PN 400
  • Process Temperature: -196 °C to +400 °C
  • Output Signal: 0.2–1.0 bar (3–15 psig) pneumatic
  • Supply Pressure: Typically 1.4–6.9 bar (20–100 psig)
  • Materials: Carbon steel, 316L stainless steel, Hastelloy C, Monel
  • Controller Action: Direct or reverse
Applications
  • Boiler drum level control
  • Separator level control
  • High-pressure vessel level
  • Interface control in refineries
FAQ

Q: Does it need electricity?

A: No – fully pneumatic.

Q: Can it replace 12400 transmitter?

A: Yes – shares the same displacer/torque-tube base.
